in Fig, 2 and by Fig. 7, maybe hinged about the pintle '29. It isunderstood that thecylin- V der block may be hinged on each sidefso thatthe block maybe swung onto either side.

The cylinder block is cast with a suitable said web portion.

What I claim is: i

1. In an internal combustio'n'engine, the

combination of a crank shaft having. a centrally'located thin webportion, a flywheel having a central opening and opposed radial slotswhereby the said crank shaft can be passed through the said opening andslots in the flywheel to effect an engagement between the saidwebportion and the said flywheel,

and means for removably securing thefsaid;

flywheel to'the sa d'web port1on..

In an internal combustion engine the combination ofa crank shaft havingan 1ntegralcentral web-portion, a flywheel having a central opening anda slot whereby the said crank shaft cangbe passed through the saidopening and slot in the flywheel to effect an engagement between thesaid web portion and the said flywheel, and means for re niovably'securing the said flywheel to the In testimony whereof I affix m Isignature.

The engine is lubricated by the well-known splash system of lubrication.As is well: knownupon ascending or descending a hill,

the oil seeks the lowest level possible; and

this often resultsv in some of the cylinders receiving airinsuflicientsupply of oil, depend I so ing upo nwhether the car is ascendingordescending a grade. In order to maintain: the, oil fromcompletely.seeking'the lowest level of the crank case when driving along a grade,I have provided the 'baflles 47 It is obvious that these baflles willmaintain. sufficient oil,
